Theuse of E-cigarette is a highly recommended remedy for the normaltobacco cigarette addicts. However, studies examining the healtheffects of E-cigarettes are very rare in contemporary medicalliterature. E-cigarettes are battery operated nicotine deliverydevices that achieve the same characteristics and feel as the normaltobacco smoking by vaporization of propylene glycol solution.Generally, E-cigarettes are composed of solution of propylene glycol,nicotine, glycerol, and flavorant chemicals. In most cases, thesolution of propylene glycol, glycerol, or a combination of both isthe most common types of liquids used in E-cigarettes. According toJansen et al. (391), formaldehyde-containing hemiacetals, which hasbeen detected by other researchers by way of Nuclear MagneticResonance Spectroscopy, can be detected during e-cigarette vaping.Traditionally, formaldehyde has been a well-known degradation producehemiacetals.

Inthis article, Jansen et al. (393) presents the results of an analysisof commercial e-liquid vaporized through the use of a tanking systemwith a variable voltage battery. The product of the utilized liquidwas collected in an NMR spectroscopy tube. From the study, it wasobserved that 5 to 11 mg of e-liquid was consumed of each puff. Atlow voltage, formaldehyde-release agents were not detected while inhigh voltage formaldehyde was detected. Using this study as thebasis, the authors argued that a normal e-cigarette user vaping at3ml per day was estimated to inhale 14.4+3.3mg of formaldehyde eachday. Previous studies have shown that inhaled formaldehyde has aslope factor of 0.0231 Kg of body weight per milligram for cancer. Inessence, increase in the level of formaldehyde in the body increasesthe risk of lifetime cancer associated with long cigarette smoking.

Whilethis article offers important insight on the effect of e-cigarette onhuman health, it has a number of weaknesses. To begin with, thevaporizing temperature in this study was not controlled to fit thatexperienced by real human subjects. As such, the high operatingtemperatures used in this study contributed to the high levels offormaldehyde detected. In addition, the thermal decompositionundergone by e-cigarette vapor is not as common as observed in thisstudy due the harsh taste experiences known as “dry puff.” In thenutshell, the study did not mimic the real environment under whiche-cigarette consumers consume the products.


Thisarticle provided a great deal of information concerning the healtheffects of e-cigarettes. Generally, e-cigarettes are provided as thebest alternative for tobacco smoking. This gives the idea that theyare safe, and healthy to consume. Unfortunately, this articledemonstrated the dangers that e-cigarettes pose to their consumers.Before reading this article, I had little knowledge on the healthconsequences of e-cigarette to their consumers. After reading thearticle, my perception concerning e-cigarettes was changedcompletely. Whether debatable or not, I am now wary about therecommended use of e-cigarettes.


Thisarticle offers a major challenge to the existing literature on theeffects of e-cigarettes on the lives of the consumers. While Ipersonally do not smoke, reading the article has influenced myperception about e-cigarettes. After reading this article, I cannotrecommend e-cigarettes for anyone wishing to quit smoking.Furthermore, in as much as the current study has variousshortcomings, the health consequences associated with inhalingformaldehyde-vaporizing agents in the body should act as a deterrentfactor for anyone wishing to start using e-cigarettes.
